Abstract :
A compact, low-cost, and low-insertion-loss millimeter-wave multiplexer design is introduced. This design uses metallic E-plane filters integrated in the septate waveguide sections of wideband E-plane n-furcated power dividers. A rigorous simulation technique, which is based on the modal scattering-matrix method, comprises the complete component including the E-plane transformer, i.e. the septum as well as the filter sections, and takes the influences of the higher-order mode interaction at all discontinuities into account. Computer optimized data are given for microwave (14.75-16.25-GHz) and millimeter-wave (74-79.5-GHz) diplexer and triplexer design examples with five-resonator, or seven-resonator metal-insert filters, respectively.<>
